is an old AS2 experiment that i made some time ago
the rules are:
- Any live cell with fewer than two neighbours dies, as if by loneliness.
- Any live cell with more than three neighbours dies, as if by overcrowding.
- Any live cell with two or three neighbours lives, unchanged, to the next generation.
- Any dead cell with exactly three neighbours comes to life.
